BUFFER FOR SWINGIEQU iNDlCATQR-L Application fi'ie-i Aprii Be it knownthat I. .liuuas H. lhxn, n citizcn of the 'lhiitcll Pitt-ties. andresident iii Xewtnn. in the rnunty of Mithllescx rind Starr 0iMaisszichnwtis. have inYt-nic-Jl new and useful llllll'lUHilihiiln inButlers for. Swinging lnthcnlur-lminus, ml which ii'icj fnllc-wing :1specific-Minn.

'lhis invcntiun relates in intlivntut devices or index devices of thekiwi wherein n nun her uf leaves or lezi i' fldlllt" nrc hinged inupright position npnn suitable. liruclicls nr standards, each leaf framehaving inwurrllv facing marginal channels in which are licl l the endsof removable and intervliargmihic indicator slips or cards, ortranspiirmi sheaths in which such slips in" cards incased. When theseleaf frames are m ring on their hinges, especially when tray or more ctthem are swung lugcthcrl with their opposed fares in engagement. and.rubbing nnc iifjiiiilil iinothvr. the inwiirtlly bent flanges of [hefllihlt't, ierining the channels, tend in tch the cdgc ct the adjacentfrznnr, therv inter-firing! with the free turning of the lmw andtwirling 50 as to lie ailjnstnlilin i'rniurnlilc and readilyinterclmngeahlc thciewith in the iraine. Such butler may also carry'as apart Of itself an in lcx tah projecting beyond the edge of the lcafframe.

Dther features of the invcntion will here inafter be tliSCl'lllQtl andparticularly poinn ed out in. the claims.

The metal strip b from which the buffer is formed may terminate at eachend, if tie-- sired, in the frame channels.

The projecting part of thestrip forming the looped tab is made of relatively broad material, thusproviding a tab 6 of suitable breadth and shape. A protective sheath 6of celluloid or other transparent material covers the tab 6 and is heldin place by tucking its ends between the two walls of the tab 7): and anindex sheet 5 on which is inscribed the desired character. is slippedbetween the metaltab 7) and the transparent covering 6 I claim 1. In anindicator device. a hinged leaf frame provided with inwardly facingmarginal channels, and-a removable strip held at its ends b saidchannels and having a buffer proiecting beyond the plane of the framesurface.

2. In an indicatrndevice. a. hinged leaf frame provided with inwardlvfacing marginal channels. and a removable strip held at its ends in saidchannels in a. position transverse to the axis of the leaf. a portion ofsa d strip being bowed outwardly to form a buffer adapted to hold thefaces of said leaf out of engagement with the next adjacent leaf.

3. In an indicator device. a hinged leaf frame provided with inwardlyfacing mar-' ginal channels. and a removable strip held at its ends bysaid channels in a position transverse to the axis of the leaf. aportion of said strip closelv adiacent to the outer margin of the leafbeing bowed outwardly to form a buffer adapted to engage the marginalframe of the next adjacent leaf and hold the same out of engagement withthe first named leaf. 7

4. In an indicator device. a hinged leaf frame provided with inwardlyfacing marinal channels. a removable strip held at its ends by saidchannels and having a buffer proiecting bevond the plane of the framesurface adapted to hold the face of said leaf out of engagement with thenext adjacent leaf, and an indicator tab carried by said stripprojecting beyond the edge of the frame.

5. In an indicator device. a hinged leaf frame provided with inwardlyfacing marginal channels, a removable strip held at its ends by saidchannels and having a buffer projecting beyond the plane of the framesurface adapted to hold the face of said leaf out of engagement with thenext adjacent leaf, and an indicator tab carried by and formed in anintegral piece with said strip projecting beyond the edge of the frame.

6. In an indicator device. a hinged leaf frame provided with inwardlyfacing marginal channels. a removable strip held at its ends by saidchannels and having a buffer proiecting beyond the plane of the framesurface adapted to hold the face of said leaf out of engagement with thenext adjacent leaf, and an indicator. tab carried by said stripprojecting beyond the edge of the frame. the face of said projecting tabbeing broader than the face of said strip.

7. In an indicator device. a hinged leaf frame provided with inwardlyfacing marinal channels. a removable strip held at its ends'bv saidchannels and having a. buffer proiecting beyond the plane of the framesurface. and an indicator tab carried bv said strip proiecting beyondthe edge of I the frame. said tab being formed of sheet material broaderthan the strip and folded back upon itself.

8. In an indicator device, a hinged'leaf frame comprising two sectionssecured back to back. provided with inwa rdly facing mar inal channels.a removable strip held at its ends by said. channels and having a bufferproiecting beyond the plane of the frame surface. and an indicator tabcarried by said strip projecting beyond the edge of the frame. said tabbeing formed of sheet material folded back upon itself to form a. flatloop. the free end of said loop being held between said frame sections.

9. As a new article of manufacture. a combined buffer and tab forindicator frames, comprising a strip of metal having an outwardly curvedportion forming a buffer, a relatively broad faced tab at one end, and atongue between said tab and buffer adapted to engage said frame, all ofsaid parts being formed of an integral strip of material.
